Endurance exercise performance: the physiology of champions

One of the first analyzes of A. V. Hill's world record in 1925 (Hill, 1925) was related to the reduction in running speed as the distance of the game became subject to muscle fatigue (Figure 1). Even before that, Italian physiologist Mosso, who was interested in fatigue of manual labor, pointed out that "This is not a will, it is not a nerve but a muscle exhausted after a hard work of the brain". His bet is commented that "brain fatigue reduces muscle strength" (DiGiulio et al., 2006).

In Hill's analysis, he revealed that the factors limiting the performance of events less than 1 minute and over 1 hour depend not only on the energy supply to contracting muscles, but also on the physiological determination of the performance from the energy storage point of view I also would argue about factors. , Oxygen demand and oxygen debt. He also speculates that there are "three types of fatigue" (which we consider to be inaccurate concepts): (1) those related to short term violence, (2) medium intensity Overcoming the body if strength lasts for a long time. Fatigue; (3) more common fatigue related to "wear". The first two kinds of fatigue are mainly considered as "muscle"

In addition, for the second and third type of fatigue that occurs during endurance exercise, Hill increases as the distance increases by about 10 miles (about 16 kilometers) or more, as the effort increases, due to the continuous decrease in the curve I guess that the second and third type of fatigue we discussed above is either a depletion of muscle material or an accidental disorder that stops people before the muscle system reaches its limit. The average weight of men running in the game must consume about 300 grams of glycogen per hour; perhaps half of them will be replaced with their equivalent fat. After a few hours, all of the body's glycogen supply is exhausted. However, it is not easy for the body to use fat alone as an energy source; metabolism may interfere; it is necessary to give carbohydrates to men so that efforts will continue. This feeding is digested; diseases of the digestive system may occur - other reactions may occur. There is no doubt that physiological principles will be determined, but we do not know enough about them and we can further analyze the curves. Studies of these comments and scandinavian physiologists of the 1930s laid the foundation for the concept of many diet and feeding strategies that have been shown to delay carbohydrate intake and fatigue (Christensen, 1939; Sherman & Costill, 1984; Murray). , 1998)

Application of physiological principle under different motor conditions Integrate the body system into exercise, work, movement and the direct and remote influences these activities have on the body. The laboratory involves measuring physiological parameters under motor conditions. Identification, evaluation, understanding and management of environmental sanitation, its impact on the environment and the environmental impact on public health. The complexity of the problem requires an interdisciplinary approach. This course will explain the principles, methods, and problems related to global environmental hygiene. In this course, we will explore the health problem, the scientific understanding of its causes, and the possible future approaches to managing major international environmental health problems.

In previous literature review on music and sports (Kravitz, 1994), physiological methods were used to study results based on evidence of various kinds of music regarding physical strength, walking, endurance performance, acquisition of motor skills . This article describes the functional and psychophysiological effects of music and movement. In addition, sidebar 1 summarizes the impression and findings of the influence on the fitness industry of world leaders in the fitness industry. Since last review, many answers have been given to scientific questions concerning music and sports, but we can say that we have not yet responded to other questions about the mechanism of music and exercise.
